Multi beam forming using FFT

I am using the phased array toolbox for the ULA and response matrix. Then taking the FFT of the response. Can you please tell me what the next steps would be to generate multi beams?

You can specify multiple directions in PhaseShiftBeamformer, the output will be the beamformed result towards those directions.

But, the number of directions is limited to only one. We want a beam split into multiple directions. I have tried it. It gives weights(w) output of dimension 2 X N. ( N is the number of directions). With these weights I cannot use plotResponse command to plot the beam pattern as it accepts only 2 X 1 matrix(single direction)

Which release are you using? The following code should have worked in recent releases.
ant = phased.ULA;
stv = phased.SteeringVector('SensorArray',ant);
plotResponse(ant,3e8,physconst('lightspeed'),'Respcut','az','Weights',step(stv,3e8,[-30 0 30]))
